I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA

I'll be here for the next 4-5 hours and then again for anther 2 hours. I'll be guided by whatever you're concerned with. Please remember that I can't provide legal advice on specific cases for obvious liability reasons since I won't have access to all the facts and documents. Please stick to a factual discussion in your questions and comments and I'll try to do the same in my answers!
